The good news is I tested all the connectivity and it is correct. The bad news is the labeling is wrong. There was no pin #7 on the main RJ45 jacks, and I had reversed all the wire color-codes: all the solid-color wires should have been rings and the white/color stripes tips. I also didn't like how the labeling appeared once it was finally on the silkscreen. And when I was fitting it to an Altoids tin, it was a pretty tight fit since the USB-A connectors stuck out pretty far. I had tested using headphone jacks with threaded barrels, and the nuts for those jacks would actually touch.

So the following are changes for the new release v1.21, 2016-Dec-4:

Wire outer pair on RJ25 jack (formerly unconnected; if you use an RJ14 or RJ11 socket or cable, it will still be.)

Move USB-A jacks inward 0.075" each.

Add a gap between the headphone jacks.

Correct color codes so solid-color wires are "rings" and white/color stripes are "tips".
